lNTRENCHlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 350,151, dated October 5, 1886.

Application filed July 7, 1986. Serial No. 207,365.

To an whom, it may concern:

Be it known that I, J oHN H. PATTERSON, an officer 0tthe United States Army, stationed and residingat Fort Assinaboine, in the Territory of Montana, have invented anew and useful Implement for Use as an Intrenching-Tool, an improvement upon that referred to and granted me in Letters Patent No. 297,640, 1884, of which (the improvement) the following is a specification.

The purpose of my invention is to provide a pick and hoe or shovel combined to be carried as a complete implement and used by soldiers on active serviceto throw up slight parapetst'ortheir protection against the fire ot'smallarms.

Figure 1 shows a view of the intrenchingtool arranged for use as a hoe or pick. Fig. 2 shows a view of the intrenching-tool arranged for use as a shovel. Fig. 3 shows a View ot the intrenching-tool when not in use, prepared for carriage by the soldier.

Referring to the drawings herewith, I describe my improvement as follows: At the top of the blade are attached two lugs with an in terval between them suflicient to permit the insertion of a wooden handle. Through the center of the lugs is a bolt-hole. In the lefthand lugthe blade viewed from the front are three smaller holes located one above, one below, and one in front of the bolthole. The

last-enumerated holes are to catch a projection (No model.)

or point upon a thumb-latch spring, which, forming part of and attached to the handle, serves to keep the handle in position for use of the implement as either a shovel, hoe, or pick, or for carriage. The lugs, made of one piece, are attached to the top of the blade by riveting the eonnectingneec to it, (the blade.) The details of the form and construction of the blade are the same as those described in Let; ters Patent No. 297 ,640, before referred to. A wooden handle, the end to be inserted between the lugs and rounded, is attached to the lugs by a be] t, which, passiugth rough the lugs, is secured in place by a nut. The handle moves freely on its axis. Attached to the handle on the left side is a thumb-spring latch with a point or projection to enter either hole in the lug when in place. The thu1nb-latch is beaded flush with the face of the handle on the Sltlt to which-it is attached.

I claim In an intrenching-tool, a blade having at its top two parallel lugs, one 01' which is perforated at its top and opposite sides, in combi nation with a handle pivoted between such lugs and bearing a catch for engaging the holes in the apertured lug, as set forth.
